AUTOMOBILE BUMrEa.

Application led March 27, 1924. Serial No. 702,336.

To all wwm t may concer/n:

Be it known that I, ANTON Jnnn, a citizen of Czechoslovakia, residing atHopkins, in the county of Hennepin and State of Minnesota, have inventedcertain new and useful Improvements in Automobile Bumpers, of which thefollowing is a specilication.

This invention relates to certain new and useful improvements inautomobile bumpers lo and has for its primary object to provide a bumperof the spring or resilient typel adapted for compression should acollision occur and tend to absorb shocks incident to a collision andfully protect the automobile equipped with the same.

A further object of the invention is to provide a bumper of the abovetype wherein spring enclosing telescopic cylinders carried by spacedbumper bars have flexible cord or cable connections between the bars forlimit ing the expansion force of the spring.

With the above and other objects in view that will become apparent asthe nature of the invention is better understood, the same consists ofthe novel form, combination and `arrangement of parts hereinafter morefully described, shown in the accompanying drawing and claimed. v

In the drawing, wherein like reference characters designatecorresponding parts throughout the several views,

Figure 1 is a top plan view of a bumper constructed in accordance withthe present invention, a portion of an automobile being illustrated bydotted lines. i

Figure 2 is a front elevationall view of the bumper,

Figure 3 is a vertical lon itudinal seetional view taken on line III- Hof Fi 1,

Figure4 is a detail sectional view ta en on line IV-IV of Fig. 2 showingthe spring enclosing tubular telescopic members carried by the bumperbars and the end connecting rod for the bumper bars,

Figure 5 is a detail sectional view taken on line V--V of Fig. 1,

iFigure 6 is a detail sectional view showing the cable connectionbetween the bumper bars, and

Figure 7 is a detail sectional view taken on line .Vfl-VII of Fig. 1.`

The spring bumper is associated with the forward ends of the side framebars 1 ofthe automobile that are illustrated by dotted lines in Fig. 1,the bumper including a rear bar 2 and a forward bumper bar 3 connectedtogether by spring devices, the mounting of the bumper frame upon theframe bars 1 of the automobile including angle brackets 4 secured to theframe bars l and further secured as at 5 to the rear bar 2 of the bumperframe;

The rear bar 2 carries a series of forwardly projecting tubular members6 while the forward bumper bar 3 lcarries rearward- 65 ly .directedtubular members 7 that telescopically receive the tubular members 6 asclearly illustrated. Coil sprin s 8 are enclosed by the telesco ing tubuar members 6 and 7 as shown in Aigs. 4=`and 7 for nor- `70 mally holdingthe forward bumper bar 3 at its limit of forward movement.

The connection between the rear bar 2 and said forward bumper bar 3includes curved rods 9 anchored as at 410 to the forward 75 bumper bar 3with the rear ends thereof v.freely passing through openings 11 formed1n the opposite ends of the rearbar 2 and carrying enlarged heads 12rearwardly of said rear bar 2 as shown in Figs. 1 and 4 80 and 5. Otherdevices for limiting the separating movement of the bumper bars 2 and 3include cord vor cable sections 13 anchored at their opposite ends aslat 14f`to the 'bars 2 and 3 as shown in Figs. 1 and 6.

From the description of the device, it is believed that the constructionand o eration thereof will at once be apparent, 1t being noted that thesprings 8 enclosed in the vtelescopic members 6 and 7 normally tend 90to separate the bumper bars 2 and 3 with the heads 12 upon the curvedrods 9 engaging the rear face of the rear bumper bar 2 while the cables13 further limit the separating movementfnfthe bumper bars. When theforward bumprbar contacts an abutment, the same moves toward the rearbar 2 causing the tubular members 6 to be tele-' scoped withinthe`tubular `members 7 and compressing the springs 8, the rear straightends of the curved rods 9 freely passing through the openings in therear bar 2 while the springs 8 absorb all shocks incident to a collisionor the like.

YWhile there is herein shown and described ythe preferred embodiment ofthe present invention, it is nevertheless to be understood that minorchanges may be made therein without departing fromthe spirit and scopeofthe invention as claimed. 310

What is claimed as new is;- exible cables attached at their op osito Ina bumper for automobiles, a rear and @IldS t0 the bumper baIS, and CurveIOdS a forward bumper bar, telescoping tubular anchored at their QUQIends t0 the OI'Wld 10 members respectively carried by the bars, bumperbal' and Shdably associated with the springs enclosed in the tubularmembers, Teal" bumpelbal means for limiting the separating movement; Intest/11110115' WheleOf I aX my Signatur@- of said bumper bars, saidmeans including ANTON JEZEK.
